With a European, and soon worldwide, phase down on HFCs, high GWP refrigerants like R410A are under pressure. While R32 has been taken up as the interim alternative for R410A in smaller splits, its flammability makes it unsuitable for use in VRF systems. Despite Honeywell’s secrecy, ...

Considering all these factors, R454B turned out to be the most suitable fluid to use in a ground source heat pump, working at given conditions. Special attention has been paid to the compression phase and the heat transfer in evaporator and condenser. Keywords: ground source heat pumps; low ...
